My invention relates to clothes wringers of the type mounted on powerdriven domestic clothes washers. Y

This is a divisional application of my application Serial No. 388,024filed April 11,` 1941.

The particular object of the invention is to provide a roll stopmechanism operable to stop the rolls upon pivotal movement of thewringer by -pressure applied on any part of the wringer. I

am aware that mechanisms have been made involving pivotal movement ofthe wringer in relation to the gear head or such similar arrangement,but such devices involve separating the gear head from the wringer andsupporting the wringer on pivotal links or the like, which introducescomplications in structure which I desire to avoid.

Another object of my invention is toprovide The complete wringer ispivotally supported on an indexing ilange casting 20 and interposedbetween the flange 2li' and the frame I0 is a pivot plate 2|, to whichthe frame I0 is pivotally attached by the pivot pin 22 on the inner endof the wringer. The wringer is normally held in l ilxed position by thetaperv plunger 23, which is means to pivotally mount a practical,unitary ,l

gear head and wringer mechanism by means which will provide a stoppageof roll rotation upon pivotal movement of the complete wringer.

I will disclose and describe the device in the following description anddrawings in which:

Fig. l is a front elevation view of the wringer complete in operatingposition, and

Fig. 2 is a top plan view of the same wringer as shown in Fig. 1 withthe oil or released position of the wringer indicated in broken dot-dashoutline.

Now referring to the drawings, and at the outset to Fig. l, I designatethe lower frame housing,

the wringer and gear headcomplete by the nu meral I0, and the upperframe by the numeral I I. Conventional wringer rolls I2 and I3 aremounted in conventional bearings in the lower frame as shown. The innerend of the top frame is mounted on the lower frame by a stationary stabclip I3, and the outer end of the upper frame is mounted on the lowerYframe by a pressure reset lever I4 and the toggle lever I5, the resetlever being pivotally mounted on the upper frame I by the pivot I6 andattached to the toggle lever I5 by the pivot I8, the toggle lever I 5pivoting on the lower frame IU by the pin I1. This is a conventionalform of frame attachment well understood in the art and will not bedescribed in further detail except to explain that the toggle lever I 5in closed position is a stable toggle which is reA leased by moving thereset lever I4 outwardly until the vtoggle pin I8 is thrown outwardlybeyond the pin I'I when the entire upper frame will be released by themovement of the toggle I5. Roll pressureis provided by a conventionalspring I3 held in pressure sustaining position by the adjustment screw20.

held in the mating notch 24 of the pivot plate 2| by the spring 25around the plunger rod 26. The plunger rod 26 is slidably mounted inbearings 21- and 28. By this structure it will be understood thatpressure applied on the frames I0 or I I will tend to pivot the frame I0around the pivot pin 22 and by the tapered notch 24 force the plunger 23outwardly against the spring 25', whereupon the'rod 26 will be movedoutwardly, pushing the reset lever I4 with it to release the toggle I5and with it the top frame I I.

Excess movement of the frame I0 is prevented by stops 29 and 30 on thepivot plate 2| as clearly shown in Fig# 2; It will beappreciated thatthe wringer is held in central position on the pivot plate 2| by theco-action between the pivot pin 22 and the taper plunger 23 in the notch24.

Now referring again to Fig. 1, the drive to the gear head is provided byconventional drive shaft 3| rotatably mounted inbearings 32 and 33 inthe indexing iiange casting 20. The shaft 3l is held by the bearings 32and 33 in the ange casting 2li' because it is necessary to provide aslotted opening 34 in the bottomof the frame II) by reason of therelative movement between the ,frame I0 and the pivot plate 2 I. Thedriveshaft 3| mounts a conventional spur gear 35 in the gear head whichmeshes with a l companion spur gear 36 Von the vertical shaft 31. Thegear 36 is fixed to the shaft 31 and .drives the clutch 38 by means oi akey 33 on which the clutch is slidable. 'I'he key 39 holds the looselower gear 36' and the upper spur gear4|| in operating relationship byco-action with the pin 40' and the collar 31'. The clutch 38 is providedwith internal gear openings 4I and 42 mating with the inner ends ot therespective gears 4I!A and 36'. whereby when the clutch 38 is actuated inone direction or another, the internal gears 4| and 42 will engage theends of the respective gears 40 and 36', whereby driving relationshipwith the shaft is established and the mating face gear 43 may be drivenin either direction at the will of the operator by moving the handle 44to force the eccentricpln 45 either upward or downward to establishdriving relationship with eithery -gear 36' or 40. This is aconventional form of drive gear head which is well understood in theart, and is believed to require no further description.

As is well understood in the art, the lower -frame must be indexedpivotally around the washing machine to provide facilities to'wring fromout of the washing machine or out of associated rinse tubs. Suchindexing is provided in my device by an indexing mechanism mounted on abracket 46 attached to the pivot plate 2|. A release latch 48 ispivotally attached to the bracket by the pin 41 and contacts an indexingpin 49 urged upwardly by the spring 50 as illustrated. The pin 49 isadapted to engage selectively in notches in the periphery of the flange29' and in coacting recess in the plate 2|. By moving the index leverupward the indexing pin 49 is moved down or out of contact with theinthe'drive shaft, a gear housing enclosing the gearing and connectedwith the wringer frame,

l mounting means for the gear housing and wringer ing engagement betweenthe drive shaft and the dexing notches 5| disposed around the flange oflease the reset lever I4 and the top frame Il, the

entire wringer, including the gear head, -will be lpivotally movedaround the pin 22, as shown in broken dot-dash outline in Fig. 2. Whensuch movement occurs in a vbackward direction, the s'pur gear 38 willassume the position shown in dot-dash outline at B. It will be notedthat such pivotal movement around pivot point 22 will move the spur gear38 out of engagement with the spur gear 35, as clearly shown in dot-dashoutline B,'and thereupon the drive to the rolls will be interrupted andtherefore the rolls will be stopped from power rotation. Similarly, uponreverse movement of the spur gear to the Point F forwardly, the sameinterruption yof the roll drive occurs, and, therefore, roll stop willbe acgearing when the wringer frame is in one position relative to themounting support and being disengaged from driving engagementtherebetween upon lateral swinging movement of said frame relativethereto.

2.' In a wringer, the combination of a wringer frame, a plurality ofcoacting rolls rotatably mounted in the frame, an upright supportingcoiumn having a drive shaft extending therethrough, mounting means forthe wringer frame including a support carried by the supporting column,means mounting the wringer frame on said support and having a pivotalconnection with said support spaced laterally from the axis of the driveshaft for swinging movement of the wringer frame eccentrically relativeto the drive shaft, and gearing connecting the rolls with the driveshaft and including a pair of gears one mounted on the drive shaft andthe other fixed relative to the frame in position for intermeshingengagement when the wringer frame is in one position and complished bypivotal movement of the-wringer in either direction.

It will be appreciated that the foree'required to accomplish thepivotal'movement as above described, may be varied by adjusting thetension of the spring 25, or angularity of the plunger 23 and itscompanion tapered notch 24.

Somel of the structure `disclosed herein is claimed in: application No.501,180, illed September3,1943. v

Having thus described my invention, I claim:

l. In a wringer, the combination of a wringer frame, a plurality ofcoacting rolls yrotatably mounted in the frame, a drive shaft, drivegearing for the rolls and operatively connected with the drive s haft, agear housing enclosing the y gearing and connected with the wringerframe, mounting means for the gear housing and wringer frame including asupport and a pivotal connection between said support and the gearhousing Vspaced laterally from the axis of the drive shaft for swingingmovement of the gear housing and wringer frame eccentrically relative tothe drive shaft, said gearing including a pair ofgears interconnectingthe drive shaft and the rolls, said pair of gears being mounted in thehousing in position for intermeshing engagement when the wringer frameis in one position relative to the mounting support and relativelymovable out of intermeshing engagement upon lateral swinging y movementof the frame relative thereto.A
